Chapter 4 Setting COM Redirector
Auto Reconnect Property
Sometimes, the connection between Advantech serial device server and HOST is
interrupted by network traffic or powered-off by accident. In such a situation, the host
has to reconnect to Advantech serial device server. The function "Auto Reconnect" is
for this purpose, if the Advantech serial server loses the connection to its host, the
COM redirector will try to re-establish the connection while the host’s AP access the
virtual COM port. The COM redirector DOES NOT re-establish the connection auto-
matically. When the connection is working again, the host's commands will be auto-
matically received by the Advantech serial device server again. Reconfiguration is
not necessary, so this function enhances the reliability of the system.
If the function is disabled, the connection cannot be re-established again unless the
COM redirector or host is restarted.
The EKI-1510 series has one Ethernet port. You can select one Ethernet port to
establish two Ethernet connections with one virtual COM port. It means that COM
redirector will use one connection with the COM port on device server to communi-
cate. If this connection failed, COM redirector will establish another Ethernet connec-
tion to communicate with device. The switch time will be 3 seconds ~ 5 seconds
depending on the network traffic and host status.
